Sorry - and I am sure I'll get people telling me the science of Apple's multitasking trying to convince me that there's no way Apps are running in the background or whatnot. But after several days of testing - there are some Apps (like Words with Friends) that are draining the battery when "not in use" but still in the quick start dock. On days that I have NOTHING in the dock, I am at between 97-100% throughout my NYC morning commute while reading with the Kindle Reader. If I have some apps in the dock during the same time frame I've gotten as low as 90-92%. Going to do some more empirical testing (one full day of not opening up one of these apps at all vs keeping one open but not using all day long) to see overall difference. So either some apps unfortunately are sucking battery life - or my phone, in particular has varied battery life. I typically come home with anywhere from 55-65% of battery left when everything is closed on the dock. On the days I've test the above, I've come home with about 30-40%. Same usages/settings/locations. Would love someone else to test to see what they come up with.
